Ars Magica 2 - Cannot unlock componets even though I have the points

Hoping this is just a small bug and someone can point me in the right direction...

I'm level 46 on Ars Magica 2, and I have the ability to do almost everything within the mod. However, even at this level (and after fighting various bosses) the Occulus WILL NOT allow me to unlock any more red skills, even though I have 6 unspent red points - see attached image.
